GHINE COMPANY, 01 NEW YORK, A CORPORATION 01' new max PRINTING TABULATOR.

Application filed larch as, 1924 Serial m. 701,941.

This invention has for its object the imrovement of printing tabulators heretofore L evised by me to the general end that certain additional functions may be performed I by the machine.

One object of the present invention resides in the provisionof means for preventing the printing or listing of each individual item when the machine is set for listing but at the same time permitting a total of the individual items to be printed at the time the machine operates to take a total.

A further object of the present invention Fig. 3 shows a part of the mechanism of the machine.

Fig. 4 is a detail of certain of the contact devices.

The circuit diagram (Figs. 1 and 2% shows the usual circuits of an electrical y controlled tabulating machine of the type now.

on the market and commonly known as the Hollerith printing tabulator. This diagram and the o eration of the machine are more fully set orth and described in my copending. application, Serial No. 639,153, filed May 15, 1923. The general'mechanism 0 this tabulator is shown in my previous Patent No. 1,379,268, to which reference may be had for a more complete understanding of the details of the machine.

In order to revent the listing of individual items wlien the machine is set for listing and at the same time to provide for the printing of totals I provide certain sup plementary controlling circuits as will now be described.

Referring first to 3 of the drawings, the shaft 355 is that s aft in my machine which is rocked during the reset cycle to rock the total-taking contacts into engagement with their stepped cams and thereby control the taking of a total- This shaft from point of function corresponds tothe shaft marked 78 in my patent heretofore referred to.

'During each totalling operation the shaft 355 m Fig. 3 is rocked in a clockwise direcing list-ing operations inasmuch as during listing, shaft 355 is in the position shown in Fig. 3.

The contacts referred to above comprise three contacts, 400, 401 and 402. They are suitably mounted upon a fixed frame member 404 and arranged to project upwardly therefrom, as shown in Fig. 3. A suitable crank arm 406 depending from the totaltaking shaft 355 carries an insulated contact actuator 407 which is arranged in alignment with the longer of the pair of contacts. Upon the rocking of shaft 355 in totalling operations, the contacts 400, 401 and 402 are all closed and durin listing these contacts all remain open, as s own in Fig. 3.

Referring now to the circuit diagram (Figs. 1 and 2) it will be noted that three non-list switches 409, 410 and 411 are provided. These switches (when open) provide for the suppressing of listing on oountersnumbere 3, 4-and 5. It will be understood that similar switches could be used on counters 1 and 2, if desired. Contacts T and T are now used in the machine and are both closed when listing, contacts T supplying current through wire 104 to common as in the former construction, connect to a lead 126 which, through individual nonars 103. Contacts T in place of f being connected to the common 'bars 125, i

list switches 409, 410 or 411, may be selectively connected to leads 412, 413 and 415, respectively, these leads extendin to common bars 103, 103'" and 125, sai bars being common bars on counters 3, 4 and 5, respectively. By closing any or all of the switches 409, 410 or 411, listing of each item will be performed as heretofore. If it is desired to suppress the listing, the particular switch 409 on any desired counter is opened thus suppressing the supply of current to the common bars during listing and thereby preventing the printing of items entered into in that particular counter. In order to efiect the printing of a total from these counters when totals are drawn on from the machine, supplementary leads 416, 417 and 418 are provided. These leads extend res ctively to the contacts 400, 401 and 402 .the common bars 103, 103 and 125 permitting a total or totals to be printed of the amounts standing on the counter. The

switch 237 is a switch heretofore provided in these machines for preventing the print-- ing of a total and is called the nontotal print switch. If this switch is opened, the machine may be arranged so as to prevent the rinting of totals when the machine is set or either listing or totalling.

The means for printing accumulated subtotals will now be described. Referring particularly to Fig. 1 of the circuit diagram,

243 is the usual reset key of the tabulator.

This key, when closed, establishes a circuit between binder post 4 and binder 0st 6 and initiates the resetting of the tabu ator. In

the present construction a pair of leads 431 and 432, are connected to these binder posts and lead to contacts 433 which are operated by a sub-total key 434. Thus the sub-total key control contacts 433 are in multiple with the usual reset contacts 243. In addition to the contacts 433, the sub-total key 434' is adapted to close supplementarysubtotal contacts 435.

In addition to the usual relays heretofore used in the machine, a so-called sub-total relay 436 is provided. Depression of subtotal key 434 energizes the sub-total rela 436, current flowing as follows: from le t side of line 82 through wire 437, contact point 438 of relay 436, wire 439, contacts 435 now closed, wire 440, to junction with the wire 441 (Fig. 2), thence back through wire 441, through the coil of relay 436, wire 442 to binder post 2, thence through clutch magnet 233, binder post 3, contacts 234, through the shunt circuit 431, 433, 432, around the reset key contacts 243. and thence to hinder post 6 and back to line. As soon as the armature of relay 436 is attracted against point 438 a holding circuit is established for the relay 436 thus permitting the release of the sub-total key 434. The circuit just traced intitiates and maintains the operation of the motor circuit for the reset motor RM just as if the usual reset key 243 were operated.

In the diagram, 128 are the usual zero button contacts. Attached to the side of these contacts which connect with the common bars 127 are supplementary leads 444 which extend to switch points adapted to connect accumulated subtotal switches 445 which are respectively connected to a lead 446 leading to the junction of wires 440 and 441.

Should it be desired to print an accumulated sub-total on any counter, the reset button of that counter is thrown out, which, through the bell crank 129 heretofore used, opens the respective contacts 128. Should it be desired to print an accumulated subtotal the desired switch 445 on the counter where an accumulated sub-total is to be printed is closed thus connecting line 446- which accumulated sub-totals are carried can be reset by shifting the reset clutch button in the usual manner.

The general arrangement of the tabulator printing devices and the resetting buttons which disconnect the resetting means are shown in my previous patent No. 1,379,268, and also shown in my copending application, Serial No. 639,153, filed May 15, 1923.
